A Muslim civil rights organization is urging Oklahomans to call their state lawmakers and urge them to vote against legislation related to State Question 755.

Last fall, 695,650 voters, 70 percent of the total, cast votes for SQ 755, which amends the state Constitution to forbid judges from considering Islamic principles or international law when deciding a case.

After the election, Muneer Awad, executive director of the Oklahoma chapter of the Council on American-Islamic Relations, acting in his capacity as an individual, filed a lawsuit challenging the constitutionality of the amendment.
